A. striata forms rosettes of hundreds of thin, narrow leaves, 60 cm (2 feet) long and 1.0 cm (0.4 inches) wide. The leaves stick straight out or arch gently upward toward the center of the plant, each ending in a very sharp, brown and black spine. The flower spike is up to 3 m (10 feet) tall and bears whitish yellow flowers 3.0-4.0 cm (1.2-1.6) inches in diameter. In the wild, numerous suckers result in thick clusters of plants growing to form impenetrable thickets.
